The weekend's 40 to 60 cm of snow rests on weak layers that the snow won't bond well to. Humans could trigger large avalanches anywhere the snow has formed a slab.
Conservative terrain travel is recommended. Riders could trigger dangerous avalanches at any elevation, on all aspects.

An avalanche cycle occurred on the weekend, with most avalanches being small to large (size 1 to 2). They were 20 to 60 cm deep and occurred on all aspects and at all vegetation bands, with the most occurring on northerly treeline and alpine features.
It remains possible for humans to trigger similar avalanches going forward.
Around 40 to 60 cm of snow accumulated since last Friday, with some wind distribution occurring in wind-exposed terrain. This snow remains soft in wind-sheltered terrain. The snow overlies various layers that it may not bond well to, including faceted grains, surface hoar crystals in wind-sheltered openings, and a hard melt-freeze crust on sun-exposed slopes.
The middle to upper portion of the snowpack between approximately 50 and 100 cm is faceted with numerous other layers of surface hoar and/or crusts that formed over the month of January.
The lower snowpack is strong.
